May Pole Knap: Petrol in a Diesel Car? Here Is What Happens

Stop. Engine off. Leave it like that — no moment on, no shifting it anywhere. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and no other factor decides that more than the next few minutes do. From now on, step by step, for anywhere around May Pole Knap:

Engine off: minute one with petrol in a diesel

First, these — in this sequence.

  • Priming the fuel system pulls petrol from your tank toward the parts it damages, and switching your ignition on can be all it takes to do that. So the keys come out, and your ignition remains off completely.
  • Don't top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mix.
  • Visibility comes before the rest near moving traffic: put your hazards on, and only then deal with everything else.
  • By hand, not on your engine: that's how it leaves the petrol pump. Get the forecourt staff to help you roll, whatever the mileage.
  • Keep your receipt. It shows which fuel went in plus about how much, which is the first thing we will ask.

Still on the move when you realised? Come off the M5 at the next junction if that is where you are, under 15 miles from May Pole Knap, and pull over somewhere sensible instead of pushing on to the services. Then start at stage one.

Has it run yet? The fork in each May Pole Knap fuel drain

From this stage on, everything hinges on a single answer.

Not run, not even briefly:

  • The petrol sits inside your tank, and just there.
  • Draining and flushing, on the spot, is normally all of it.
  • No position is better, and it's why the first step matters so much.

If your engine has run, even briefly:

  • The fuel lines and the filter already carry petrol drawn out of your tank.
  • The high-pressure pump as well as the injectors see it too on a longer run.
  • The further it went, the bigger the job — the fuel lines, the fuel filter, and now and then more besides.

Petrol does not lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line sits where it does. In the tank, sitting still, petrol harms nothing. Move the petrol, though, and it grinds down the very parts that move it.

Before you call about petrol in a diesel in May Pole Knap: what our technicians need

Whether the van goes round or finds you comes down to a little planning.

  • TA11 6 plus the remainder of the postcode is the ideal way to start telling us where you are.
  • Name the street — Sevenacres or wherever you have stopped — or the car park.
  • Name a car park by what it serves — the one at Londis, for instance — and it is much quicker to find.
  • The vehicle. Make, model, and that it's a diesel.
  • Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate May Pole Knap page.
  • About how much — in litres from the receipt, or by how long the nozzle stayed in.
  • Whether it's run. Then if it has, how far and how hard.
  • The owner may have to approve the work under some hire and company agreements — which is why it is faster to settle whose car it is before our engineers get there.

Phone 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use .

Whilst you wait for a fuel drain in May Pole Knap

Stick to these: well-meant help does the damage during the wait.

  • Your safety comes before the car. Somewhere unsafe? Get away from the traffic and wait away from it. Fine where it is? Wait with it.
  • No one — however helpful — starts it, whether to see if it runs or to move your car a short way.
  • None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
  • No DIY emptying. Siphoning petrol into a can at the roadside is dangerous, and it leaves your fuel that has by now gone beyond your tank.
  • Even your radio or your windows aren't worth switching the ignition on for.

The fuel drain, step by step, after the van arrives

  • First, three questions: which fuel got in, the volume, and has it run? Those replies set this job, so the price follows them.
  • Clearing it's how that blend gets taken from your tank.
  • Rinsing the fuel lines follows, because a vehicle that ran has petrol past your tank, in the fuel lines themselves.
  • Then the filter: swapped where there is a workable one, cleared where there's not.
  • The fuel system is primed with clean diesel.
  • The start-up. With fresh diesel in and the system bled, it's fired up and tested to be sure it runs correctly.

Our engineers stay until it is running on clean diesel. Permanent damage is very unusual when it has been noticed soon, so the vehicle can go straight back to normal use.

After your fuel drain: back on the road in May Pole Knap

  • Nothing unusual is needed after a start with clean diesel — normal driving is all.
  • Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over and ring us back.
  • Hold on to the paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out.
  • Next time, go by the petrol pump's label instead of the colour of its handle.
